/// An iOS-style text field.
///
/// A text field lets the user enter text, either with a hardware keyboard or with
/// an onscreen keyboard.
///
/// This widget corresponds to both a `UITextField` and an editable `UITextView`
/// on iOS.
///
/// The text field calls the [onChanged] callback whenever the user changes the
/// text in the field. If the user indicates that they are done typing in the
/// field (e.g., by pressing a button on the soft keyboard), the text field
/// calls the [onSubmitted] callback.
///
/// To control the text that is displayed in the text field, use the
/// [controller]. For example, to set the initial value of the text field, use
/// a [controller] that already contains some text such as:
///
/// {@tool sample}
///
/// ```dart
/// class MyPrefilledText extends StatefulWidget {
///   @override
///   _MyPrefilledTextState createState() => _MyPrefilledTextState();
/// }
///
/// class _MyPrefilledTextState extends State<MyPrefilledText> {
///   TextEditingController _textController;
///
///   @override

///     _textController = TextEditingController(text: 'initial text');
///   }
///
///   @override
///   Widget build(BuildContext context) {
///     return CupertinoTextField(controller: _textController);
///   }
/// }
/// ```
/// {@end-tool}
///
/// The [controller] can also control the selection and composing region (and to
/// observe changes to the text, selection, and composing region).
///
/// The text field has an overridable [decoration] that, by default, draws a
/// rounded rectangle border around the text field. If you set the [decoration]
/// property to null, the decoration will be removed entirely.

  /// count two characters, and the second case will be counted as one
  /// character, even though the user can see no difference in the input.
  ///
  /// Similarly, some emoji are represented by multiple scalar values. The
  /// Unicode "THUMBS UP SIGN + MEDIUM SKIN TONE MODIFIER", "👍🏽", should be
  /// counted as a single character, but because it is a combination of two
  /// Unicode scalar values, '\u{1F44D}\u{1F3FD}', it is counted as two
